PAD HOLDER AND ADJUSTABLE CLAMP Filed June 29. L928 INVENTOR AITTOIRNEY Patented Sept. 17, 1929 UNITED STATES PATENT OFFICE WILLIAM c. HIERING, or NEWARK, NEW annsnmassrenon To J. E, MERGOTT (20.,

F NEWARK, NEW JERSEY, A [CORPORATION OF DELAWARE PAD HOLDER AND ADJUSTABLE CLAMP Application filed June 29,

This invention relates to holders and means for retaining paper sheets thereon.

Devices of thisjcharacter are a necessary convenience where numerous thin sheets of material are to be held in orderly arrangement, such for instance as papers, either loose and unconfined or connected in pad form, such as calendars,memorandum pads, lists, bills, etc, but as such sheetsare usually sub ject to change in number, and consequently their combined thickness, by addition of new sheets and removal of those which have been used or become obsolete, as in the case of a calendar,provision should be made to adjust the clamping means to accommodat such varying conditions.

One of the objectsof the present invention is to provide means whereby a spring clamping device may be conveniently raised and lowered relative to the plate support on which the sheetsrest, so that a few sheets may be held as firmly as a far greater number.

A further feature is in the provision of a pad support possessing unusualmerit in its design and structure whereby strength, economy in material and neatness in appearance are secured.

These important objects are accomplished by the novel design, arrangement and combination of parts, hereinafter described and illustrated in the accompanying drawing, forming an essential portion of this disclosure, andin which Figure 1 is a perspective view looking from the outer side and rear end of apad support as made in accordance with the invention, showing its application to a thick pad.

tails of construction in perspective and in the relation they will assume when assembled.

A flat sheet metal sub-base plate, generally designated by the numeral 10, cut in the shape of an oblong rectangle orotherwise to suit its purpose, has formed near one end, in its under side, a shallow transverse raised panel 11,

in the end portions of which are sheared prongs 12 extending rearwardly at right angles, and containing end slots 11'.

Figure 3'is a view showing the several de- 1928. Serial 'No. 289,216.

Fitting the panel 11, and level with the under surface of the sub-base plate 10, is a plate 13 having depressions 14: suited to reeeive the prongs '12, which are entered through openings 15 at the outer ends of the depressions 14 and are afterwards turned and upset to fill the same smoothly, holding the plates rigidly in fixed relation. 1 I

Integral with the ends of the plate 13 are outstanding right angular brackets 16, their rear edges extending outwardly beyond the corresponding edge of the plate, and formed in the brackets, adjacent their rear edges, are longitudinal slots 17, straight'at the back and having in their front edges a series of slightly undercut notches 17 17 17.

, Spaced parallel from the slots, in the front portion of the brackets are similar "slots 18, having straight, forwardly extending notches 1818 18, and directly opposite the notch 18", in the rear edge of the slot is an inreaching ledge'19. a I

An upper baseplate 20 is shaped. in contour to the sub-base 10, uponwhich its depressed margin 21 isseated, the inturned edges 22 of a felt fabric intervening, this fabric enveloping the edges of the sub-base 10 and extending completelyover its entire outer area, constituting a cushion surface 23 to prevent' abrasion of whateverthe pad support may rest upon. a i

The plate 20 has narrowlongitudinal slots 24; neatly fitting the brackets 16 which are first passed through the slots 11" in theplate 10, thence the slots 24, theplate 20being rigidly held to the sub-base plate 10 by rivets 25 passed through openings 26 in the plate 20 and corresponding openings 27 in the plate 10, these latter openings being formed in raised nipples 28 in the plate. these openings receiving the rivet heads so that'no projection interferes with the felt cushion 23.

The paper pad X is pressed against the level surface of the plate 20 by a clamping member 30, preferably curved convexly to present spaced contacting edges disposed longitudinally in the direction of the length of the pad, the clamping members being integral with an angular down-reaching plate connection 31 leading to a fiat table 32.

Reaching rearwardly from the element 32 are wings 33, their upper, downwardly ininclined upper edges having reentrantly turned, inbent hooks 34, and in their semicircularly curved ends are openings 35. 1

Another sheet metal frame member 36 is curled to produce a tube 37 at one of its edges, suited to fit between the brackets 16 and headed pins 38 tightly driven into the tube ends after passing through the slots 17 in which the pins are freely movable.

The opposite edge of the'member 36 is curled outwardly to form a guard 39, further on explained, and extending forwardly'from the ends of the member 36 are plate levers 4E0 engageable closely adjacent withinthe wings 33 and containing openings d1 registrable with the wing openings A tube 42 is held in alinement with the openings 41 by headed pins 43 passing impinge on the element 31, causing the clamping member 30 topress firmly on papers X.

When the clamping member and its unitary members have pivoted on the pins l3 until the leverstO engage the loops 34;, further clamping effect is arrested and it be comes desirable to move the pivots 43 and 38 from the outer notchesl8 and 17 to the intermediate notches 18 and 17 and ultimately to the lowermost notches 18 and 17 in order to maintain a substantially uniform pressur on the sheets remaining on the plate 20.

Shifting of the pivots is readily accomplished by drawing the same outwardly into the slots 18 and 17 respectively and transferring to the other notches as required, and it will be noted that the shape of the rear notches is such as to prevent inadvertent movement, which is also guarded against by the projections 19. 7

Obviously the clamping member 30 is released by applying sufficient pressure to overcome the tension of the spring elementsin the usual manner;

'From the foregoing it will be seen that a simple device for this purpose has been disclosed in the preferred form of its embodiment, but it is not desired to restrict the details to the exact construction shown, it being obvious that changes, not involving the exercises of invention, may be made without conflicting with the scope of the appended claims. 7 7

Having thus described the invention, what is claimed as newand desired to secure by Letters Patent, is r 1. A pad holder having a surface to receive a pad, a spring actuated clamping member to press the pad against the surface, an adjusting member on said surface, and means removably secured to said clamping member to adjustably'position said clamping member in said adjusting'member relatively to said surface.
